10 1 10 Introduction Jacking Systems Screw jacks can be connected together in systems so that multiple units can be operated and controlled together. These jacking system arrangements or configurations can be built in many formats with the use of bevel gearboxes, motors, reduction gearboxes, drive shafts, couplings, plummer blocks and motion control devices. Four of the most popular system configurations are the H, U, T and I configured jacking systems. Note that multiple screw jacks can be linked together mechanically or electrically. The latter is useful if there is no space for linking drive shafts. a a Screw Jack E-Series Rotating Machine Screw Jack shown here.. Bevel Gearbox Range-N Spiral Bevel Gearboxes 3. Flexible oupling A range of couplings are available to suit each systems requirements including Jaw, Spacer and Geared types. 4. Drive Shaft Every drive shaft is manufactured to order for each system design. Self supporting drive shafts (spacer couplings) are also available. 5. Shaft Supports (plummer blocks). 6. Electric Motor Standard electric motors in 3 phase, 1 phase, D and servo designs. Supplied as a basic motor or as part of a geared motor. Brakes are available for all motors.

11 Introduction Jacking Systems 1 11 Jacking systems are not limited to the number of screw jacks shown here. They are regularly supplied to clients with, 4, 6, 8 jack systems. Larger systems can extend up to 16 or higher. With the use of electronic synchronisation/control multiple systems or screw jacks can be used in unison. Extending the possible number of screw jacks used in unison in excess of 100. To facilitate electronic control of screw jacks, feedback devices (eg encoder, limit switch) are available, mounted on the screw jack or its motor or another system component. a a a

16 1 16 Introduction Selecting a Screw Jack Five Step Guide to Initial Screw Jack Selection The following selection procedure is applicable for Machine Screw and Ball Screw Jacks. alculate Power and Torque Requirements Select a screw jack from the tables with adequate load carrying capacity and note the screw jack static and dynamic efficiency for required input speed. Step 1 - Screw Jack Input Speed N (rpm) = Linear Speed (mm/min) x Gear Ratio Pitch (mm) x N of Starts on Lifting Screw Input speed should not exceed 1800 rpm. Number of starts on lifting screw is usually 1, unless otherwise stated. Note: Screw Lead = Pitch x No of Starts Step - Operating Input Power (kw), P in P in (kw) = Load (kn) x Linear Speed (mm/min) x d d = Dynamic Screw Jack Efficiency Step 3 - Operating Input Torque T ino (Nm) = P in (kw) x 9550 N (rpm) Step 4 - Screw Jack Start-Up Torque T ins = Load (kn) x Pitch (mm) x N of Starts on Lifting Screw x x s x Gear Ratio s = Static Screw Jack Efficiency Note: Screw Lead = Pitch x No of Starts Step 5 - Mechanical Power and Torque heck heck whether the screw jack power and torque required for the application is not greater than the maximum allowable mechanical input power (P mechanical ) and Start-Up Torque at Full Load (T s ) values specified in the screw jack performance tables. If P mechanical > P in & T s > T ins then the screw jack selected is acceptable for power requirements.

17 Introduction Selecting a Screw Jack 1 17 Example Selection Application onstraints Load on Screw Jack = 15 kn in Tension Linear Speed required = 100 mm/min onsider all application constraints then choose a screw jack that looks suitable for the application with a load rating equal to or greater than the maximum working load. For this example, a 5 kn E-Series Machine Screw Jack (refer P60) with translating screw, 6:1 gear ratio, single start lifting screw (6 mm lead). alculate Power and Torque Requirements Step 1 - Screw Jack Input Speed N (rpm) = r p m 100 (mm/min) x 6 (Gear Ratio) N = (mm) x 1 (N of starts on Lifting Screw) Input speed should not exceed 1800 rpm. Step - Operating Input Power (kw), P in P in (kw) = i n 15 (kn) x 100 (mm/min) d = 0.64 (Refer P60) x 0.64 P = kw Step 3 - Operating Input Torque T ino (Nm) = (kw) x (rpm) T ino = 9.1 Nm Step 4 - Screw Jack Start-Up Torque T ins = 15 (kn) x 6 (mm) x 1 (N of starts on Lifting Screw) T ins = 11.9 Nm x x 0.01 x 6 (Gear Ratio) s = 0.01 (refer P60) Step 5 - Mechanical Power and Torque heck Find the screw jacks mechanical power and torque rating from the performance data tables (refer P60). P mechanical = 1.5 kw > P in and T s = 19 Nm > T ins Therefore the screw jack selected is suitable for application for initial constraints tested, further analysis may be required to ensure the screw jack is suitable for all application conditions. ontinue with further selection calculations or consult Power Jacks Ltd.

18 L L L 1 18 Introduction Selecting a Screw Jack Screw Jack onstraints for Detailed Selection Lifting Screw olumn Strength For compressive loads on the screw jack lifting screw column strength calculations are required to check for buckling. As a screw jack selection guide use the following process: 1. Determine the maximum column strength (L) for the screw jack being considered.. Referring to the relevant column buckling chart determine the permissible compressive load (Wp) corresponding to the column length (L) for the appropriate end constraints. This permissible compressive load is the maximum load (inclusive of shock loads) which may be applied to the screw jack for a given column length. 3. Where an application involves human cargo or there is a risk to personnel, it is highly recommended that the permissible compressive load (as calculated above) be factored by 0.7 to enhance working safety. (Equivalent to a column strength safety factor of 5). W phc = W p x 0.7 (Permissible compressive load for personnel risk applications) Note 1. For detailed analysis of screw jacks and their systems consult Power Jacks.. Safety factor of 3.5 for column strength s used for normal industrial cargo. Lifting Screw ritical Speed For fast operating rotating screw jacks, the critical speed (rotational speed) of the lifting screw needs to be considered in case of shaft whirling. To calculate the critical speed for rotating screw jacks: 1. Refer to the appropriate critical speed chart.. Select the correction factor F cs corresponding to the end support conditions for the application. 3. From the critical speed chart, select the critical speed corresponding to the unsupported screw length (m) and the screw jack load rating (kn). 4. alculate the limiting critical speed with the formula: Limiting ritical Speed = ritical screw speed x F S Lifting Screw Deflection The lifting screw of a screw jack mounted horizontally will deflect under its own weight to some extent. The amount of deflection tolerable (y T ) should be less than 0.5 mm per metre. Deflection Factors, F sd Fixed/Fixed. F sd = 8 Fixed/Fixed. F sd = 186 Fixed/Fixed. F sd = 384 Deflection, y, (mm) = 6 x 10-9 x L 4 Deflection Tolerable, y F sd (d-p) T, (mm) = 0.5 x L 1000 L = Lifting Screw Length (mm) d = Diameter of Lifting Screw (mm) p = Pitch of Lifting Screw (mm) If y < y T then the lifting screw deflection is acceptable. Note: This is only a deflection guide. For detailed analysis, including methods to reduce deflections, consult Power Jacks Ltd.

19 Introduction Selecting a Screw Jack 1 19 Screw Jack Input Torque Start up/static torque values are listed in all performance tables. Whereas dynamic torque values are either calculated using the tabulated dynamic efficiencies or taken direct from torque tables where listed. For detailed screw jack analysis consult Power Jacks Ltd. Side Loads on Screw Jacks It is recommended that all side loads (F sl ) are carried by guides in your arrangement and not by the lifting screw and nut. If there are any side loads on the screw jack, they must not exceed those tabulated in the Engineering Guide, Side Load Rating Section, and it must be noted that any such loads will adversely affect the life of the lifting screw and nut. Radial Forces on Screw Jack Worm Shaft For applications where a screw jack is belt driven, radial force (F R ) values exerted on the worm shaft must not exceed those tabulated in the Engineering Guide Section. Values are tabulated for the metric machine screw jacks and ball screw jacks. The values are maximum values for the screw jacks at rated load regardless of worm speed or load direction. Screw Jack Self-Locking Approximately 50% of machine screw jacks are self-locking either in the gearbox or the lifting screw, however to ensure there is no selflowering and to reduce drift due to the motor slowing, a brake is recommended. Standard motor frame size brakes will be suitable for most applications with only slight vibration and thermal fluctuation present. Motor selection as normal. For dynamic braking consult Power Jacks. Use the closest standard brake size that is greater or equal to the motor brake torque required. Note 1. Self lowering can occur in any jacking system not fitted with a brake, where high levels of vibration are present in the application.. Power Jacks recommend the use of a brake on single screw jack applications in the vertical position. Jacking System Power Input Total Input Power for Jacking Systems (kw), P s : P s = Input Power per Screw Jack (kw) x Number of Screw jacks Arrangement Efficiency x Gearbox Efficiency Number of Screw Jacks in System Jacking System Efficiency Gearbox Efficiency = Bevel Gearbox Efficiency x Reduction Gearbox Efficiency Bevel Gearbox Efficiency = 0.95 typical Reduction Gearbox Efficiency = onsult unit details, if no reduction gearbox present assume efficiency of 1. Note For Screw Jacks connected in-line, the worm shaft can transmit up to 3 times the torque for a single screw jack at its maximum capacity, except the E--000 (00kN) Unit which can transmit 1.5 times the torque.

52 5 E-Series - Machine Screw Jack Anti-Backlash Minimise Axial Backlash for Reversing Loads The Anti-Backlash feature provides a reliable method to regulate the axial backlash in a screw jack for applications where there is a reversal of loading from tension to compression. The amount of backlash between the screw and worm gear nut can be adjusted (adjust shell cap) to a desired amount or a practical minimum. To avoid binding and excessive wear do not adjust backlash to less than 0.05mm. The Anti-Backlash feature also acts as a safety device, providing dual nut load carrying unit, when the worm gear becomes worn. A visual wear indicator is available on request for all models and a feeler gauge can be used to measure the wear. This can be upgraded to use a sensor for wear monitoring. onsult Power Jacks for either option.

58 58 E-Series - Machine Screw Jack Safety Nuts Extra Safety for ritical Applications Load Load Power Jacks machine screw jacks can be fitted with a safety nut, which provides safety roles: 1. In the event of excessive wear on the nut thread the load will be transferred from the standard nut to the safety nut. This will also provide visual wear indication as the gap between the safety nut decreases to zero as the standard lifting nut wears.. In the unlikely event of catastrophic nut thread failure the safety nut will sustain the load. The safety of industrial and human cargo is therefore improved. There are several configurations for each safety nut device as they only work in one load direction. For this reason when ordering please supply a sketch of your application showing load directions.
